Kris Jenner has revealed that daughter Khloe Kardashian has been pro-active in keeping younger sisters Kylie Jenner and Kendall Jenner on the right path as they get older.

The Keeping Up with the Kardashians star said that while she has always been a hands-on parent, her older daughters Khloe, Kim Kardashian and Kourtney Kardashian have also tried to ensure that their teen siblings don't get into trouble.

"Little kids, little problems. Big kids, big problems. I remember calling [my former sister-in-law] when Kourtney was 5 months old to say, 'This is so hard - I've been folding cloth diapers for days!' At the time I thought, 'Nothing can be harder than this!' Boy, was I wrong," Jenner told Family Circle.

"[The older girls] drill messages into their sisters' heads so they won't make the same mistakes. But it's Khloe who checks the younger girls' e-mails and texts to make sure they're not up to anything inappropriate."

Jenner also revealed her family's motivation for being so forthcoming on their multiple reality shows, adding: "We wouldn't be the Kardashians if we censored ourselves."
